--- Comment #18 from David Edelsohn <dje at gcc dot gnu.org> ---
As long as GCC claims that it can make a distinction between the various
alignments and macros, the GCC code generation must continue to honor it.

On AIX, at least, the ABI claims a different stack alignment with and without
Altivec.
